The Science

A synergistic blend of skincare actives and superfoods

Squalane

A must-have skincare active for hydration, squalane is a biomimetic, mimicking the scalp’s natural sebum to rehydrate the hair and condition coloured strands from the inside out.

Açai Extract

A superfood rich in polyphenols and omegas, açai fruit smooths the cuticle and enhances elasticity to fight the frizz lightening can cause, protecting blondes from brittle strands.

Moringa Oil

Rich in antioxidants and oleic acid, moringa oil strengthens blonde hair against the everyday stressors that cause colour fading and brassiness. Because blonde hair shouldn’t be fragile hair.

Argan Oil

Known as ‘liquid gold,’ argan oil is rich in linoleic acid and vitamin E, replenishing the fatty acids and moisture stripped by bleach and colour to make blonde hair softer, shinier, golden.
